The idea

mocha-insights-reporter is a reporter for mocha. It gives you performance matrix of your app based on each test cases duration.

it creates logs whenever you run tests with this reporter included.
you don't have to change your code to integrate this reporter.
usually run silently and wont output wired stuff to console and make it ugly.
by default, it generates mocha-insights directory in your application root (you may gitignore this directory).
every logs and reports will be stored there.
separate logs and reports for different NODE_ENV environment.
run mocha-insights to compile the report from logs.

How to setup?

step 1: get stuffs

You need the following dependencies to get this running.

mocha : our awesome test framework,
mocha-insights-reporter : (this package) and
mocha-multi : get multiple reporters working with mocha

Get them all.

step 2: integrate

Assumptions

Assuming you are already using the default spec reporter. Else change the setup accordingly. Its simple.
Assuming your tests are at ./tests directory.

Setup

open your package.json

create or modify your test and insights tag under the scripts section as follows.

"scripts": {
		....
		"test": "./node_modules/.bin/mocha ./tests --recursive --reporter mocha-multi --reporter-options spec=-,mocha-insights-reporter=-",
		"insights": "./node_modules/.bin/mocha-insights",
        ....
}

Note that mocha-insights-reporter needs to output end result to the console. So please use ... mocha-insights-reporter=- while using with mocha-multi.
